TypeScript Generics

Generics:

Generic is a type which connected to other type, where we don't know what type of data it will return

//Generics

const names :Array<string> = []; //which is similar to string array as const names: string[]

Promises:

Anothor example is promise method, which allows to two arguments in a method and return string type array.

Promise is a built in generic type in typescript

const promise = new Promise() // which is a constructor function.

Syntax example

const promise: Promise<string> = new Promise((resolve, reject) => {

    setTimeout(() => {

        resolve("This is my code");

    },1000)     

});

promise.then(data => {

    data.split(' ');

});
